1/23? It is almost 1/4 the size of a FF sensor. So all tjings being equal, the FF sensor gives you a clearly better image. A small body, mch smaller than a DSLR FF is possible of course. But smaller lenses not. So I wonder what the incentive is really. To my mind, the best argument would be:

- smaller body,- smaller lenses- similar IQ.

What m43 has currently with APS-c DSLRs (to my mind of course). But we'll see. Always nice to see somehting new and a mirrorless cam with such a large sensor is very welcome regardless!

I actually wrote 1/23, haha! You are correct.

Things will rationalize in the next couple of years. M43 is ideal for most people who want smaller size, portability yet decent images and interchangeable lenses. Not for most pros except as second cameras. Sony is in a partnership with Olympus, and may have secretly agreed to drop the small NEX square APS-C bodies so Olympus can thrive with their successful m43 program. Instead according to my new conspiracy theory of to-day, Sony has shifted over to APS-C and FF larger bodies.
